CoolDry field test result
19.7.2010 / 14.7.2010 in Ludwigsburg, South Germany
Outside temperature peak 36 °C, sunny, light breeze
Changing temp readings / partly inconsistent data due to clouds, breeze
Concrete plates 40 x 40 cm, 6 cm strong, light grey
- Chart A: Concrete with Membrane
- Chart B: Back of Concrete with Membrane
- Chart C: Concrete (bare)
- Chart D: Comparison Front/Back
The back of the untreated plate is nearly as hot as the front – powerful heating system! Even at 21.30 it is still above 30 °C.
Interesting: the back of the concrete is cooler than the front for quite some time
